Generally, the rheological characteristics of rock and coal have been often described using creep models, such as the Maxwell model (Jiang et al., 2009; Zhu et al., 2006), the Cvisc model (Liu et al., 2010; Jiang et al., 2008) and the Burgers model (Huang et al., 2006), etc.
On the other hand, in order to properly represent the rheological deformation behavior of the underground structure associated with mining, the Cvisc model is selected.
A Cvisc model, also called a Burger-creep viscoplastic model in FLAC3D, is characterized by a visco-elasto-plastic deviatoric behavior and an elasto-plastic volumetric behavior.
